Swift has been only too happy to help.įor most of its short life, CIPS went largely unnoticed. So far, CIPS has opted not to go the extra step and create its own Swift-like messaging system, preferring to collaborate rather than compete with its far larger rival. It lets global banks clear cross-border yuan-denominated transactions directly onshore, rather than in clearing houses located in offshore yuan hubs such as Hong Kong. The result was the Cross-Border Interbank Payment System (CIPS), run by the People’s Bank of China. In 2015, a year after Russia annexed Crimea, leading to a first wave of US and EU sanctions, China set out to create its own version of Chips. All have US offices and are privy to US law, making it easy to catch and penalise offenders. Chips is a private club comprising 43 financial institutions, which collectively settle $1.8 trillion in claims every day, using a pre-funded account at the Federal Reserve. Swift is based in Belgium, but has a data centre in Virginia. The three pillars of the US financial system are the dollar, Swift (the main cross-border communications channel for banks), and the Clearing House Interbank Payments System (Chips). I also love to hear how you use this in your applications.It has also failed to make much of a dent in the US’s financial hegemony. I welcome comments and suggestions on improving the code. I hope it has been useful and if so please share with others. This example shows how to start using the share sheet based on the content. I am using the simulator so share options may be different. Click the button and the keyboard should disappear and share sheet should appear. func displayAlert(title: String, message: String) ) We will call the method with a title and message, add the following func to the view controller. We are going to keep the code tidy by separating the creation and display of the Alert in a separate method. ![]() If you are not familiar with the UIAlertController then I recommend my article ‘ Display an Alert or Action Sheet Using Swift in iOS 8‘. We will check if the text field is empty and if it is just alert the user giving them instructions to enter something and try again. The share sheet should only show if there is something to share. The button needs to handle any possible out comes and handle them gracefully. I also added constraints to keep the layout nice and pretty regardless of the device. Next create an each in the view controller. I added them to a storyboard from the object library. Now add a text field and a button using your method of choice. Start by creating a Swift based iOS application in Xcode. We are going to create an iPhone application with a text field to enter some text and a button that shares the contents using share sheet. One thing to remember, on iPhone you present the sheet as a modal view but on the iPad you have to present it as a popover. It is worth noting that you can override the options iOS gives you but we will not cover that this time around. You only need to tell iOS what you want to share and it will present only those options capable of handling the content you send to it. It is not hard to add this feature to your Swift applications thanks to iOS. ![]() That is when the magic of the sharing sheet appears. ![]() You find a great piece of content and want to Tweet it, post it to Facebook or maybe just email to a friend. To achieve this in applications you can use the UIActivityViewController. A nice feature on iOS is the ability to share just about anything to anywhere using the built in sharing system.
