Standard Approach, using a DateFormatter 🗓 As mentioned, the DateFormatter approach set's up the timezone, set's up the string format for the date, and then uses the formatter to provide the string from Foundation's date object! Looking at this a bit more in-depth, notice that the timeZone on the formatter is set to the.current timeZone. Converting a Date instance to a string using one of the built-in time formats. Converting a Date instance to a string using a completely custom format. Converting a string instance to a Date. Below are examples of each to get you started. First, this converts a Date to a short date string using dateStyle: let today = Date let formatter1. Question or problem with Swift language programming: Swift’s JSONDecoder offers a dateDecodingStrategy property, which allows us to define how to interpret incoming date strings in accordance with a DateFormatter object. However, I am currently working with an API that returns both date strings (yyyy-MM-dd) and datetime strings (yyyy-MM-dd HH:mm:ss), depending on the property.

SWIFT message types are the format or schema used to send messages to financial institutions on the SWIFT (Society for Worldwide Interbank Financial Telecommunication) network. The original message types were developed by SWIFT and a subset was retrospectively made into an ISO standard, ISO 15022. In many instances, SWIFT message types between custodians follow the ISO standard.^[1] This was later supplemented by a XML based version under ISO 20022.

Composition of MT number[edit]

Date, Swift has its own Date type. No need to use NSDate. Creating a Date and Time in Swift. In Swift, dates and times are stored in a 64-bit floating point number Creating Date in Swift using Date Create a date with current date and time. Let currentDate = Date //Saturday, November 25, 2017. SWIFT message types are the format or schema used to send messages to financial institutions on the SWIFT (Society for Worldwide Interbank Financial Telecommunication) network. The original message types were developed by SWIFT and a subset was retrospectively made into an ISO standard, ISO 15022.

SWIFT messages consist of five blocks of data including three headers, message content, and a trailer. Message types are crucial to identifying content.

All SWIFT messages include the literal 'MT' (message type). This is followed by a three-digit number that denotes the message category, group and type. Consider the following two examples.

Example 1

Steam download steam final fantasy 14 ps4. MT304

The first digit (3) represents the category. A category denotes messages that relate to particular financial instruments or services such as precious metals (6), treasury (3), or traveller's cheques (8). The category denoted by 3 is treasury markets
The second digit (0) represents a group of related parts in a transaction life cycle. The group indicated by 0 is a financial institution transfer.
The third digit (4) is the type that denotes the specific message. There are several hundred message types across the categories. The type represented by 4 is a notification.

A MT304 message is considered an 'Advice/Instruction of a Third Party Deal' and it used to advise of or instruct the settlement of a third party foreign exchange deal. ^[2] For example, an asset manager who executed a FX transaction with a broker would send a MT304 instruction to the custodian bank of the client.

Example 2

The first digit (1) represents the category. The category denoted by 1 is customer payments and cheques.
The second digit (0) represents a group of related parts in a transaction life cycle. The group indicated by 0 is a financial institution transfer.
The third digit (3) is the type that denotes the specific message. There are several hundred message types across the categories. The type represented by 3 is a notification.

A MT103 message is considered a 'Single Customer Credit Transfer' and is used to instruct a funds transfer.^[3]

Overview of SWIFT MT categories[edit]

The table below shows the different categories and the message type descriptions.

Category	Message type	Description	Number of message types
0	MT0`xx`	System messages	-
1	MT1`xx`	Customer payments and cheques	19
2	MT2`xx`	Financial institution transfers	18
3	MT3`xx`	Treasury markets	27
4	MT4`xx`	Collection and cash letters	17
5	MT5`xx`	Securities Markets	60
6	MT6`xx`	Treasury markets – metals and syndications	22
7	MT7`xx`	Documentary credits and guarantees	29
8	MT8`xx`	Traveller's cheques	11
9	MT9`xx`	Cash management and customer status	21

ISO 15022 MT[edit]

Although ISO 15022 message types are different in their structure than the SWIFT MT, the naming convention remains the same.

Question or problem with Swift language programming:

Swift’s JSONDecoder offers a dateDecodingStrategy property, which allows us to define how to interpret incoming date strings in accordance with a DateFormatter object.

However, I am currently working with an API that returns both date strings (yyyy-MM-dd) and datetime strings (yyyy-MM-dd HH:mm:ss), depending on the property. Is there a way to have the JSONDecoder handle this, since the provided DateFormatter object can only deal with a single dateFormat at a time?

One ham-handed solution is to rewrite the accompanying Decodable models to just accept strings as their properties and to provide public Date getter/setter variables, but that seems like a poor solution to me. Any thoughts?

How to solve the problem:

Solution 1:

There are a few ways to deal with this:

You can create a DateFormatter subclass which first attempts the date-time string format, then if it fails, attempts the plain date format
You can give a .customDate decoding strategy wherein you ask the Decoder for a singleValueContainer(), decode a string, and pass it through whatever formatters you want before passing the parsed date out
You can create a wrapper around the Date type which provides a custom init(from:)
