iOS Swift - Cancellable Task with GCD

#iOSBySheldon

I think most of you guys know GCD pretty well. Basically, GCD is a high level API to handle multi-threading operations. We use GCD almost on daily basis to switch thread and execute codes like:

DispatchQueue.main.async { //execute some codes here } 
//switch to main queue and execute codes asynchronously

DispatchQueue.main.sync { //execute some codes here } 
//switch to main queue and execute codes synchronously

Symbolicate iOS crash manually
View symbolicateiOS.md

Step 1: Use the following command in Terminal to find the dSYM on your Mac which build the app

mdfind "com_apple_xcode_dsym_uuids == 12345678-90AB-CDEF-1234-567890ABCDEF"

The string "12345678-90AB-CDEF-1234-567890ABCDEF" is the UUID string from the crash report reformatted to uppercase and 8-4-4-4-12 groups.

Step 2: Symobolicate Crash Report. Excute the following line before symbolicating
