| - [ ] How many projects do you have | |
| - [ ] Which architectures approaches do you use | |
| - [ ] Which swift version / legacy objc, c what are you going to do with it. | |
| - [ ] Do you do layout in xibs or in code? | |
| - [ ] What do you think about reactive programming (RxSwift) |
Use these steps to debug components of the Swift toolchain. This allows you to see Swift's source code from the debugger – instead of disassembly. The debugger can also provide some variable names and values. This has been initially tested with libswiftCore.dylib.
These instructions were updated as of Swift 5.2.1.
