I am using Xcode Project Renamer to rename my Xcode project, after that I used the code below to install pod file.
It's working good but the terminal showing result after pod installed. I want to show result while installing the pod.
#discardableResult
private func shell(_ command: String) -> String {
let task = Process()
task.launchPath = "/bin/bash"
task.arguments = ["-c", command]
let pipe = Pipe()
task.standardOutput = pipe
task.launch()
// pipe.fileHandleForReading.readDataToEndOfFile()
let data = pipe.fileHandleForReading.readDataToEndOfFile()
let output: String = NSString(data: data, encoding: String.Encoding.utf8.rawValue)! as String
return output
}
let command = shell("pod install")
print(command)
Can someone help please.

I want to programmatically open a terminal and paste a command into it like "cd /Users/...".
I can start a terminal using this code, but I don't know how to execute command
guard let url = NSWorkspace.shared.urlForApplication(withBundleIdentifier: "com.apple.Terminal") else { return }
let path = "/bin"
let configuration = NSWorkspace.OpenConfiguration()
configuration.arguments = \[path\]
NSWorkspace.shared.openApplication(at: url, configuration: configuration, completionHandler: nil)
It is very important to use the sandbox, the Process command is not suitable.
If all you are trying to achieve is to open a terminal on a specific location all you have to do is to use this code:
let pathToOpen = "/Users/admin/Desktop"
let url = URL(string:"terminal://"+pathToOpen)!
NSWorkspace.shared.open(url)
If you are trying just to run a command in terminal and show the output in your app, here is another useful code snippet:
func shell(_ command: String) -> String {
let task = Process()
let pipe = Pipe()
task.standardOutput = pipe
task.standardError = pipe
task.arguments = ["-c", command]
task.launchPath = "/bin/zsh"
task.standardInput = nil
task.launch()
let data = pipe.fileHandleForReading.readDataToEndOfFile()
let output = String(data: data, encoding: .utf8)!
return output
}
//Usage:
shell("yourCommandHere")
//please note that you are not allowed to use commands that require sudo
I am looking for a solutuion to run shell commands in a Swift script.
Here is my code:
func shellEnv(_ command: String) -> String {
let task = Process()
let pipe = Pipe()
task.standardOutput = pipe
task.standardError = pipe
task.arguments = ["-c", command]
task.launchPath = "/bin/zsh"
task.launch()
let data = pipe.fileHandleForReading.readDataToEndOfFile()
let output = String(data: data, encoding: .utf8)!
return output
}
It works with built-in commands but it cannot deal with commands like "brew", "node" and other commands that were installed manually.
So how can I solve it?
You need to set the PATH environment variable for the task. This has been set in your terminal, which is why you are able to do brew and node and other cool things directly, without specifying their full path.
You can see what this is set to in your terminal by doing:
echo $PATH
and it will print something like (for me it has a bunch more things. This is only an excerpt):
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
If you copy and paste the entire output of echo $PATH, and put it into the environment property of task, then you will be able to use the same commands in your swift script as in your terminal.
task.environment = ["PATH": "<paste the output here>"]
As Alexander said in the comments, another way is to add the l option. Here is a MCVE:
#!/usr/bin/swift
// main.swift
import AppKit
func shellEnv(_ command: String) -> String {
let task = Process()
let pipe = Pipe()
task.standardOutput = pipe
task.standardError = pipe
task.arguments = ["-cl", command]
task.launchPath = "/bin/zsh"
task.launch()
let data = pipe.fileHandleForReading.readDataToEndOfFile()
let output = String(data: data, encoding: .utf8)!
return output
}
print(shellEnv("brew list")) // assuming you have brew
To run, chmod +x main.swift then ./main.swift, and you will see all your homebrew packages listed.
I want to create Daemon (Plist in ~/Library/LaunchAgents/) from my macOS application.
import Foundation
func shell(_ command: String) -> String {
let task = Process()
let pipe = Pipe()
task.standardOutput = pipe
task.arguments = ["-c", command]
task.launchPath = "/bin/bash"
task.launch()
let data = pipe.fileHandleForReading.readDataToEndOfFile()
let output = String(data: data, encoding: .utf8)!
return output
}
// Example usage:
shell("ls -la")
I know using this I can create a daemon but at this location
~/Library/LaunchAgents/
I am not able to create due to permission issues. Operation not permitted
But using terminal I am able to Create Plist inside
~/Library/LaunchAgents/
Wanting to get a details of all installed applications by executing system_profiler SPApplicationsDataType
The snippet given below works just fine in playground, however gives me code signing internal problem: unexpected error from xpc when I try executing it from an application.
func shell(_ command: String) -> String {
let task = Process()
task.launchPath = "/bin/bash"
task.arguments = ["-c", command]
let pipe = Pipe()
task.standardOutput = pipe
task.launch()
let data = pipe.fileHandleForReading.readDataToEndOfFile()
let output: String = NSString(data: data, encoding: String.Encoding.utf8.rawValue)! as String
return output
}
print(shell("system_profiler SPApplicationsDataType"))
P.S Apologies if this is a dumb question, I'm fairly new to swift and xcode technologies :)
I am trying to execute shell commands from swift program. below is my program
func executeCommand(command: String, args: [String]) -> String {
let task = Process()
task.launchPath = command
task.arguments = args
let pipe = Pipe()
task.standardOutput = pipe
task.launch()
let data = pipe.fileHandleForReading.readDataToEndOfFile()
let output: String = NSString(data: data, encoding: String.Encoding.utf8.rawValue) as! String
return output
}
When I use the path as /bin and try to execute ls command it works and prints the output. but when i try to run
executeCommand(command: "export DEVELOPER_DIR=\"/Applications/Xcode.app/Contents/Developer/\"", args: [""])
it is not working. I tried to find the location of export but terminal says it is inbuilt. How do i execute the export DEVELOPER_DIR from my swift program?
