Matching string characters

Code

func allCharactersPresent(_ str: String, _ str1: String) -> Bool {
    var charc = Array(str)
    var charc1 = Array(str1)
    var charPresent = false

    for i in 0..<charc.count {
        charPresent = false
        for j in 0..<charc1.count {
            if charc[i] == charc1[j] {
                charc1[j] = "."
                charPresent = true
            }
        }
        if !charPresent {
            return charPresent
        }
    }
    return charPresent
}
