A simple stopwatches use to logging out the elapsed time between 2 timestamp, easily find out execution time of any function, a block of code or async callback.
Add below line to your project Podfile
pod 'Watches'
Then run pod install from Terminal
Drag and drop Watches.swift source file into your project
By default, Watches will automatically print out the debugging log in format
"Elapsed interval for \(identifier) is \(interval)"
If you want to disable this auto log feature, set
Watches.printElapsedTimeAutomatically = false
Track elapsed time of any async callback (e.g : network request) call tick to tickoff the time with specific identifier right before calling async task
Watches.tick("LoadProfile")Then call tock with the corresponding identifier inside async callback closure
Watches.tock("LoadProfile")For example with Alamofire
Watches.tick("LoadProfile")
Alamofire.request(loadProfileUrl).responseJSON { response in
Watches.tock("LoadProfile")
}It will print out the elapsed intervals in default format
Result: Elapsed interval for LoadProfile is 1.20113898515701
Feel free to provide custom format that you desire
Watches.tock("LoadProfile") { debugPrint("Time needed for \($0) is \($1)") }
If you want the elapsed interval for your own purpose, get it from the tock return value
//You can disable auto print feature if you want
Watches.printElapsedTimeAutomatically = false
//Then get the result from tock function
let elapsedTime = Watches.tock("LoadProfile")
Determine the execution time of any block of code.
Watches.create("1 million times loop").tick {
//Block of code to measure
for _ in 0...10000000 { }
}.tock()Result: Elapsed interval for 1 million times loop is 0.214788019657135
If you want custom print format, just need to provide the tock callback closure.
Watches.create("2 million times loop").tick {
//Block of code to measure
for _ in 0...20000000 { }
}.tock { debugPrint("Time for finishing \($0) is \($1)")}Result: Time for finishing 2 million times loop is 0.411646008491516
If you just want to get the result
let executionTime = Watches.create("MyClosure").tick {
//Block of code to measure
sleep(3)
}.tock()
debugPrint(executionTime)Result: 3.0011550188064575
