How to print call stack in Swift?

As Jacobson says, use the following:

Swift 2:

print(NSThread.callStackSymbols())

print(Thread.callStackSymbols)

That's Swift code. It's using a Foundation method, but so does 90%+ of what you do on iOS.

Note that the formatting looks better if you use:

Thread.callStackSymbols.forEach{print($0)}

From the debugger command line you can type

e Thread.callStackSymbols.forEach{print($0)}

swift debugging callstack

For Swift 3 use:

print(Thread.callStackSymbols)

or for better formatting

for symbol: String in Thread.callStackSymbols {    print(symbol)}

swift debugging callstack

This improves the output a little.

for symbol: String in NSThread.callStackSymbols() {    NSLog("%@", symbol)}
