Question 1

How do I add libextobjc to my Xcode project?

Accepted Answer

You need to use git submodules or subtree merging as described in the README, then manually include the source files in your project. There's no built-in support for package managers, so it requires more setup than typical dependencies.

Question 2

Can I use libextobjc with Swift code in my app?

Accepted Answer

Yes, via Objective-C bridging headers, but libextobjc is designed for Objective-C and its macros and patterns may not translate seamlessly to Swift's syntax, limiting its usefulness in mixed codebases.

Question 3

What are the alternatives to libextobjc for Objective-C?

Accepted Answer

For similar safety features, consider libraries like ReactiveCocoa for reactive patterns, but libextobjc is unique in its modular compile-time checks. For dependency management, CocoaPods or Carthage offer easier integration for other libraries.

Question 4

libextobjc vs using plain Objective-C categories?

Accepted Answer

libextobjc's safe categories prevent method overwrites with conflict detection, whereas plain categories risk runtime collisions. It also adds extra features like compile-time key paths, but requires more setup.

Question 5

How to avoid retain cycles in blocks with libextobjc?

Accepted Answer

Use the @weakify and @strongify macros from the EXTScope module to create weak references before blocks and strengthen them inside, ensuring safe memory management without manual weak variable handling.

Question 6

Does libextobjc work with manual memory management?

Accepted Answer

No, the library requires ARC and explicitly states that MRR usage is not supported, so it's incompatible with projects that don't use automatic reference counting.
