How to run Terminal commands from cocoa app? - swift

Question

I have problems running a Terminal command from a Cocoa Application.
The input for the Terminal is real easy: /Users/.../Csvmidi </Users/.../test.csv> /Users/.../Melody.mid
These are three inputs- three actual paths - are just written in a row and seperated by a spac: the first "Csvmidi" runs a Unix Application which converts the test.csv to an actual hearable MIDI file. Through the terminal it works perfectly...
I just don't get it to work via a Cocoa Application.
let process = Process()
process.executableURL = URL(fileURLWithPath: "/bin/zsh/")
process.arguments = [lblCsvmidi.stringValue,"<"+lblURL.stringValue+">",lblMidi.stringValue]
//I saved the URL of the UNIX program, test.csv and Melody.mid in a lable just to be sure.
//lblCsvmidi --> URL of Csvmidi UNIX program
//lblURL --> URL of test.csv
//lblMidi --> URL of Melody.mid
print(lblCsvmidi.stringValue,"<" + lblURL.stringValue + ">",lblMidi.stringValue)
// this print command was only made to check the arguments in the terminal if they would work --> they do
process.terminationHandler = { (process) in
print("\ndidFinish: \(!process.isRunning)")
}
do {
try process.run()
} catch {}
When I run the code it gives me either the error of an 75: unmatched", but actually there isn't a quotation mark in the command - or I get "permission denied" errors.
I tried several bin folders like ( I really tried almost every possible):
- /bin/zsh
- /bin/csh
- /bin/ksh
- ...
What am i doing wrong --> I haven't found information in other Questions here and the Process, NSTask and Bundle informations from Apple haven't helped me so far.
Thanks!!

The following runs without error on my system:
import Cocoa
let process = Process()
process.executableURL = URL(fileURLWithPath: "/bin/zsh/")
var args : [String]!
args = []
args.append("-c")
args.append("open '/Users/xxxx/Desktop/myApp.app/Contents/MacOS/myApp'")
process.arguments = args
process.terminationHandler = { (process) in
print("\ndidFinish: \(!process.isRunning)")
}
do {
try process.run()
} catch {}
let app = NSApplication.shared
app.setActivationPolicy(.regular)
app.activate(ignoringOtherApps:true)
app.run()
The strings after "-c" would depend on what you are trying to accomplish.
