Ios swift – How to convert string with pipes | | into dictionary

I have a string with many pipes I want to convert them into dictionary [String:Any] how can I do that ?

Example

let input = "boolFirst=false|onProject=Active|passed=false"

Into -->

let output = [String: Any] = [boolFirst: false, onProject: "Active", passed: false]

so far tried with components(separatedBy: "|") & components(separatedBy: "=")
Is there any cleaner way to achieve ?

    U can try the following code.

    let input = "boolFirst=false|onProject=Active|passed=false"

var output: [String: Any] = [:]

let pairs = input.components(separatedBy: "|")
for pair in pairs {
    let components = pair.components(separatedBy: "=")
    let key = components[0]
    
    if components[1] == "true" {
        output[key] = true
    } else if components[1] == "false" {
        output[key] = false
    } else {
        output[key] = components[1]
    }
}

print(output)

    Output Printed —

    ["onProject": "Active", "passed": false, "boolFirst": false]

    We can use the swift Regex and RegexBuilder functionality for this.

    The regex would be

    let regex = Regex {
        Capture {
            OneOrMore(.word)
        } transform: { substring in
            String(substring)
        }
        "="
        Capture  {
            OneOrMore(.any)
        }
    Optionally {
        "|"
    }
}

    and then convert the result of matching the regex to a dictionary by using reduce(into:)

    let output = input.matches(of: regex)
    .reduce(into: [String:Any]()) { $0[$1.output.1] = $1.output.2 }
