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.

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: 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.

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.

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

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

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?
