Formatted call stack symbols for iOS.
Supports Swift Package Manager.
let symbols = CallStackSymbols.current()let parser = CallStackSymbols.DLADDRParser()
let callStackSymbols = Thread.callStackSymbols
for callStackSymbol in callStackSymbols {
let dladdr = try parser.parse(input: callStackSymbol)
// ...
}DLADDR is struct defined here.
This library internally call Thread.callStackSymbols. Documentation of Thread.callStackSymbols says Each element is an NSString object with a value in a format determined by the backtrace_symbols() function.
Information about backtrace_symbols() can be seen by $ man backtrace_symbols and manual says backtrace_symbols() attempts to transform a call stack obtained by backtrace() into an array of human-readable strings using dladdr().
Detail of dladdr() can be seen by $ man dladdr. The information treated by dladdr() contains 2 set of name and address. The values returned value by Thread.callStackSymbols cannot read as-is because raw value is array of string. So I defined struct DLADDR and parse raw string into that formatted structure.
