Question 1

How do I install GCDTimer with Swift Package Manager?

Accepted Answer

The README only provides Carthage instructions; for SPM, you might need to add the GitHub repo manually, but official support isn't documented, so check the repository for updates or use Carthage as specified.

Question 2

GCDTimer vs NSTimer: which is better for iOS apps?

Accepted Answer

GCDTimer is more reliable than NSTimer as it uses GCD to avoid run-loop issues, but NSTimer might suffice for simple use cases. GCDTimer offers better lifecycle management and test coverage, as highlighted in the README.

Question 3

How to handle timers when the app goes to background with GCDTimer?

Accepted Answer

The README suggests manually pausing timers in applicationWillResignActive, so you must implement this logic yourself—GCDTimer doesn't automatically manage background states.

Question 4

Can I use GCDTimer in SwiftUI projects?

Accepted Answer

Yes, GCDTimer works in SwiftUI apps, but you'll need to manage state and lifecycle within SwiftUI, such as using @State or Combine, since it's a plain Swift library.

Question 5

Is GCDTimer thread-safe for concurrent access?

Accepted Answer

The README doesn't specify thread safety; while it's built on GCD, caution is advised when accessing timers from multiple threads without explicit documentation.

Question 6

How to cancel a GCDTimer delay before it executes?

Accepted Answer

GCDTimer.delay doesn't seem to have a built-in cancellation method based on the README; you might need to manage this externally, such as using flags or other GCD mechanisms.
