如何将枚举大小写传递给使用'if case‘检查属性大小写的函数

enum CaseSensitiveEnum {
    case UPPERCASE
    case lowercase
    case MixedCase
}

func checkPropertyCase(property: CaseSensitiveEnum) {
    if case .UPPERCASE = property {
        print("Property is in UPPERCASE.")
    } else if case .lowercase = property {
        print("Property is in lowercase.")
    } else if case .MixedCase = property {
        print("Property is in MixedCase.")
    }
}

let property1 = CaseSensitiveEnum.UPPERCASE
let property2 = CaseSensitiveEnum.lowercase
let property3 = CaseSensitiveEnum.MixedCase

checkPropertyCase(property: property1) // Output: Property is in UPPERCASE.
checkPropertyCase(property: property2) // Output: Property is in lowercase.
checkPropertyCase(property: property3) // Output: Property is in MixedCase.
