I have created a Swift framework that creating a button programmatically, and the action of the button is showing a webView and close it, my framework works fine in Swift project but in Objective C it just create button but it is not taking action and does not show my webView, Note: I am getting the button configuration from server via JSON using SwiftyJSON
below is the my Swift Class in addition to SwiftyJSON in the framework project
import Foundation
import UIKit
import WebKit
@objc public class predictionButton : NSObject {
public override init(){
}
var buttonConfigApi = "XXXXXXXXX"

var webViewHeight = CGFloat()
@objc public var globalView = UIView()
var parseFlag = Bool()

@objc public func addButtonPredict(view: UIView, phone: String, token: String){
parseJSON()
sleep(5)
var phonTok = "{'a':\(phone),'b':\(token)}"
let utf8str = phonTok.data(using: String.Encoding.utf8)
let data = (phonTok).data(using: String.Encoding.utf8)
let base64 = data!.base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0))
var finalURL = String()
self.globalView = view
finalURL = "\(self.indexURL)?d=\(base64)"
self.globalURL = finalURL
let button = UIButton(frame: buttonPosition(view: view, alignValue: buttonAlignment))
print((self.globalURL))
button.backgroundColor = hexStringToUIColor(hex: self.buttonBackgroundColor)
print("global color value \(buttonBackgroundColor)")
button.setTitle("\(self.buttonText)", for: .normal)
button.setTitleColor(hexStringToUIColor(hex: self.buttonTextColor), for: .normal)
let buttonFontSize = 15
let buttonTitleSize = (buttonText as NSString).size(withAttributes: [NSAttributedString.Key.font : UIFont.boldSystemFont(ofSize: CGFloat(buttonFontSize + 1))])
button.frame.size.height = buttonTitleSize.height * 2
button.frame.size.width = buttonTitleSize.width * 1.5
view.addSubview(button)
button.tag = 5
button.addTarget(self, action: #selector(nest), for: .touchUpInside)
}
@objc func nest (){

extension UIColor {
convenience init(red: Int, green: Int, blue: Int) {
assert(red >= 0 && red <= 255, "Invalid red component")
assert(green >= 0 && green <= 255, "Invalid green component")
assert(blue >= 0 && blue <= 255, "Invalid blue component")
self.init(red: CGFloat(red) / 255.0, green: CGFloat(green) /
255.0, blue: CGFloat(blue) / 255.0, alpha: 1.0)
}
convenience init(rgb: Int) {
self.init(
red: (rgb >> 16) & 0xFF,
green: (rgb >> 8) & 0xFF,
blue: rgb & 0xFF
)
}
}
extension String {
var numberValue:NSNumber? {
let formatter = NumberFormatter()
formatter.numberStyle = .decimal
return formatter.number(from: self)
}
}
and I have created a Objective-C and add the built framework in it and its .m file code is below :
#import "ViewController.h"
@import myFrameWork;
#import <myFrameWork/myFrameWork-Swift.h>
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
predictionButton *btn = [[predictionButton alloc] init];
[btn addButtonPredictWithView:self.view phone:@"XXXXXXX"
token:@"XXXXXXXXXXXXXXXXXXXXXXXXXXX"];
}
@end
Note: this framework works fine in Swift project
Here is working swift code:
import UIKit
import myFrameWork
import WebKit
class ViewController: UIViewController {
var button = predictionButton()
override func viewDidLoad() {
super.viewDidLoad()
button.addButtonPredict(view: self.view, phone: "XXXXXXXXXX", token: "XXXXXXXXXXXXXXXXXXXXXXXXX")
}
