I'm kind of getting some more understanding with basic SwiftUI but now I wanted to extend my application to actually do some stuff regarding system components for me. Basically I want to run an AppleScript from inside my app which creates a signature in Mac Mail. The script itself is pretty simple:
// Generates a signature in Mac Mail
tell application "Mail"
set newSig to make new signature with properties {name:"The Signature Name"}
set content of newSig to "My New Signature Content"
end tell
I have created a view with a button which should execute the script:
import SwiftUI
struct SomeView: View {
@State var status = ""
var body: some View {
VStack(alignment: .center) {
Button(action: {
let source = """
tell application \"Mail\"
set newSig to make new signature with properties {name: \"The Signature Name\"}
set content of newSig to \"My New Signature Content\"
end tell
"""
var error: NSDictionary?
if let scriptObject = NSAppleScript(source: source) {
if let output: NSAppleEventDescriptor = scriptObject.executeAndReturnError(&error) {
self.status = output.stringValue ?? "some default"
} else if (error != nil) {
self.status = "error: \(error)"
}
}
}) {
Text("Generate").font(.callout)
}
Text("\(self.status)")
}
}
}
struct SomeView_Previews: PreviewProvider {
static var previews: some View {
SomeView()
}
}
Everything executes but I get the error
AppleScript run error = {
NSAppleScriptErrorAppName = Mail;
NSAppleScriptErrorBriefMessage = "Application isn\U2019t running.";
NSAppleScriptErrorMessage = "Mail got an error: Application isn\U2019t running.";
NSAppleScriptErrorNumber = "-600";
NSAppleScriptErrorRange = "NSRange: {0, 0}";
}
After some research i found this article which describes the problem quite well. Apparently this error is because the app is running in a sandbox and within the sandbox Mail is indeed not running. I kind of get Apple's idea not to let applications do whatever they want without the user's consent...
Anyway, unfortunately this article describes the solution using Objective C and this is something I have even less of a clue than SwiftUI.
Can anybody tell me how to run (or copy my script.scpt file to the accessible library folder and the run) a script from within a SwitUI View? This would be so much help!
Thanks!!!
