I'm about 2/3 into the 100 Days of Swift course and this is gold! First, because it will help me navigate and follow the projects quick and easily, and second, because I came here just curious, expecting not to understand most of it, but I do understand almost all of it, and that makes me feel like I really progressed in my understanding of iOS programming.
Absolutely excellent Paul. My favourites: 1. In storyboard, Hold the Option key and then select the Source code file which makes sure that assistant editor is opened with the right file to make your connections 2. To go back to the file list no matter where the navigator panel is currently - Command + 1 3. Shift + Command + K to clean the build folder. Apparently Shift + Option + Command + K is supposed to perform a deeper clean. No idea if this is fact or fiction. 4. Command + R to run, Command + B to build 5. Mulit-position editing. Select the first location then hold Shift + Control then select the other locations to edit. Massive time saver. That should do for the moment.
Paul you are a legend, thanks for sharing these, 10 years doing Xcode development and didnt know half of these - My current fave is "Run without building" when you just want to restart the app without re compiling "ctrl+cmd+r"
Favorite additional tips: CMD-Shift-Y to show/hide the debug area and Option-click on view controller when in the storyboard to display on screen and drag button actions over. Great series!
The spelling check and the extended mini map navigation will be a game changer in my daily developer routine. Thanks for the excellent video. You are an awesome guy.
So many good tips! I love the Structure > Move Selection Up or Down feature with cmd+opt+[ or cmd+opt+]. Works for both a single line of text, or many! Even more useful when writing SwiftUI
Great tips! Knew some of them. One tip for SwiftUI that I am careful to follow, is to not type too much code before building because the error messages don’t make sense so you can’t pinpoint which line of code is wrong until you start deleting all the lines you entered until you find the one.
My tip: the disabled breakpoints also leaves a blue line on the right scrollbar. Just click twice in front of your actually important lines and work with a quick visible reference on the scrollbar. You can remove them after work done, from the Breakpoint Navigator.
The tip about adding init to classes is also useful for structs. the member wise init provided by the compiler is always “internal”. If you want a public one you can: Change your object from struct to class, use the Xcode refactoring tool to generate the init, change it back to a struct... and then make the generated init public.
My tip for you guys is something some may know from the JetBrains IDEs. They have this little target icon above the file tree and if you press it, it will show you where the currently in the editor opened file is located in the file tree. This is very useful in large projects after you navigated in your editor by clicking on method names for example. I missed it so long in Xcode until I found out it has it too, but it's little bit more hidden. You have to right click in the editor, then -> Navigate -> Reveal in Project Navigator
Haven't watched alll the vid yet, so don't know If it comes up, but here's the best thing I ever did for myself in Xcode. I bound the Refactor->Rename option to F13. Now I just place the cursor over a variable or function name, F13, write new name, enter. Boom, renamed everywhere
Its good but got a bad thing when using with swiftlint, If you have an empty space (between two line for readability ) it will add space and create a warning for swift lint
Even better, there is an option in Xcode which will automatically re-indent on paste. You can find it in File > Preferences > Text editing > Indentation > Check "Re-indent on paste"
⇧⌘J - select the visible file in project navigation, was a real discovery for our team. Really help to navigation throw complicated architecture try it! Cheers
No. 5 was that I was don't know before, that's really helpful. But what for i was hoping was "DUPLICATE CURRENT LINE", its really handy shortcut when when needed declaration of same type and modifier variable.
Thanks for the tips, I learned 2-3 new life-savers ❤️ I like to move things, and so do I like to move code in my source file. Mostly when dragging around some piece of useful code ⌥ + CMD + [ -> move line up ⌥ + CMD+ ] -> move line down
Number 1 is lifesaver, thank you for this video. I will be using it and number 8. Some i didn't know about, some did. Can anyone recommend some videos about testing?
@@trendz4422 it’s only really useful when browsing through others code, it’s gives you a birds eye view of what’s going on. Otherwise you would have to figure out what each component does and individually
14:43 NumberedRow.init???? I guess this is Swift being really clever, but can you please show the expanded version that shows how the unnamed List value is passed to the NumberedRow view?
My favourite is the 'Quicken' feature to help speed up builds. If you are finding build projects slow (especially Unity builds for me) press CMD + Q whilst XCode is buiilding the project and it will allocate more system resources to that task
Okay, but how can I force Xcode’s code editor to ALWAYS insert 2 spaces (or however many I want in the preferences) whenever I hit the key? This is super aggravating when I want to tab over an opening ‘{‘ and nothing happens. 😫 Even better, is there some way to have it put the open curly brace on the next line after a “func” declaration, and indented one level?
Does anybody know why Xcode puts generated initializer or protocol conformance methods BEFORE other declaration bun not AFTER. Maybe to train us to not forget cmd-x cmd-v? )))
7:00 Blow my Mind!! Thanks

Great tips, the auto spelling and grammar is my favorite
"Which is useful for the NEVER times you want to print out your source" 🤣
0:28 was just something I was bemoaning about classes yesterday! Thanks!
My favorite Xcode shortcut is selecting part of code and choosing refactor extract it to method. Makes code so clearer.
I like the triple slash comment that provides a description for a function or class when using autocomplete

Multiline Editing in Xcode is one of the most mind blowing features I have ever seen.
So many good tips! I love the Structure > Move Selection Up or Down feature with cmd+opt+[ or cmd+opt+]. Works for both a single line of text, or many! Even more useful when writing SwiftUI
When was this added?
@@adlsfreund the feature has been there for a long time. The shortcut appeared in 2014 I believe.
Astoundingly helpful! Thank you, Paul.
I loved that tip about generate initializers!
Dbl click the brace is defo gonna help. Am forever scrolling up and down trying to find matching braces.
My tip is to always check your explanation first when I want learn something new with Swift.

i've learnt so much from this man it's not even funny anymore
Awesome! Learned many new useful things! Thank you, Paul!
Thanks. All tips are usefull. Tiling the simulator is most useful tip for me from all the new tips I learn.
That indent shortcut is going to save me a lot of time.

Any tip for showing and hiding line numbers without to open the preferences?
This is gold!!!
Thank you so much Paul 🙏🏻🙏🏻🙏🏻
Do you have a debugging tips 101 video?
Cmd shift o - nice shortcut
These were so, so great.
Documenting a method shortcut is a great tip for me, hopefully I'll be doing it more often now on :)
Great video, thanks!
Probably the best Xcode tips list I've ever seen. I knew like only 2 of these, so the rest were pure gold :)
Fantastic tips - thanks Paul! :-)
These are really helpful!
Nice tips!
Very useful, thanks!
Thank you for all the tips
Thanks for sharing this.. Really cool tips & tricks.
Excellent. Thank you.
Please make a video on Swift UI MVVM programing 🙏🏼
for tip No1, I find it more easy not to use the Editor, you can simply do right click on the class name -> refactor > generate membervise initializer
Thanks for these tips!
Very good tips!
Thanks Paul!
Very useful. 🤘
Amazing tips
could u make a vid making a player with multiple videos with the play next button plz i can't figure it out

I know it's not part of Xcode but it's worth.
Hey paul, how do you add the preview or simulator that when you change code it changed the app live like in swiftui
Great tips 👍
Like all of it ✨
@Paul Hudson can I create a story in the medium for this? and tag the youtube?
My favourite one is All issues fixing in one click
Now if this would also work in Jira 😌
Thanks Paul
TIP 3: Double Click i searched lot. Thanks Paul..!!!
That was so extremely useful, thank you very much Paul. Those were some pretty advanced pro tips there!
I like Multi-cursor editing.
should have been tip #25
Brilliant - thanks
I love auto-indent --> ctrl-I ;-)
cmd+. - Stop current build/run task
cool!
Thank you! ..... Now we need one of your subscribers to have a print out for us lol
Thanks paul 👏
