Adhan Swift is a well tested and well documented library for calculating Islamic prayer times. Adhan Swift supports Swift 4.0, Swift 4.2, Swift 5.0 and Objective-C.

All astronomical calculations are high precision equations directly from the book “Astronomical Algorithms” by Jean Meeus. This book is recommended by the Astronomical Applications Department of the U.S. Naval Observatory and the Earth System Research Laboratory of the National Oceanic and Atmospheric Administration.

Implementations of Adhan in other languages can be found in the parent repo Adhan.

Manual

You can also manually add Adhan.

  • Download the source.
  • Add Adhan.xcodeproj as a subproject in your app's project.
  • Drag Adhan.framework to "Linked Frameworks and Libraries" in your app's target.

Usage

To get prayer times initialize the PrayerTimes struct passing in coordinates, date, and calculation parameters.

let prayers = PrayerTimes(coordinates: coordinates, date: date, calculationParameters: params)

Initialization parameters

Coordinates

Create a Coordinates struct with the latitude and longitude for the location you want prayer times for.

let coordinates = Coordinates(latitude: 35.78056, longitude: -78.6389)

Date

To avoid confusion with timezones the date parameter passed in should be an instance of DateComponents. The year, month, and day components need to be populated. All other components will be ignored. The year, month and day values should be for the local date that you want prayer times for. These date components are expected to be for the Gregorian calendar.

let cal = Calendar(identifier: Calendar.Identifier.gregorian)
let date = cal.dateComponents([.year, .month, .day], from: Date())

Calculation parameters

The rest of the needed information is contained within the CalculationParameters struct. Instead of manually initializing this struct it is recommended to use one of the pre-populated instances by calling the params var on the CalculationMethod enum. You can then further customize the calculation parameters if needed.

var params = CalculationMethod.moonsightingCommittee.params
params.madhab = .hanafi
params.adjustments.fajr = 2
ParameterDescription
methodMember of CalculationMethod enum
fajrAngleAngle of the sun used to calculate Fajr
maghribAngleAngle of the sun used to calculate Maghrib, used for some Calculation Methods
ishaAngleAngle of the sun used to calculate Isha
ishaIntervalMinutes after Maghrib (if set, the time for Isha will be Maghrib plus ishaInterval)
madhabMember of the Madhab enum, used to calculate Asr
highLatitudeRuleMember of the HighLatitudeRule enum, used to set a minimum time for Fajr and a max time for Isha
adjustmentsPrayerAdjustments struct with custom prayer time adjustments in minutes for each prayer time

CalculationMethod

ValueDescription
muslimWorldLeagueMuslim World League. Fajr angle: 18, Isha angle: 17
egyptianEgyptian General Authority of Survey. Fajr angle: 19.5, Isha angle: 17.5
karachiUniversity of Islamic Sciences, Karachi. Fajr angle: 18, Isha angle: 18
ummAlQuraUmm al-Qura University, Makkah. Fajr angle: 18.5, Isha interval: 90. Note: you should add a +30 minute custom adjustment for Isha during Ramadan.
dubaiMethod used in UAE. Fajr angle: 18.2, Isha angle: 18.2.
qatarModified version of Umm al-Qura used in Qatar. Fajr angle: 18, Isha interval: 90.
kuwaitMethod used by the country of Kuwait. Fajr angle: 18, Isha angle: 17.5
moonsightingCommitteeMoonsighting Committee. Fajr angle: 18, Isha angle: 18. Also uses seasonal adjustment values.
singaporeMethod used by Singapore. Fajr angle: 20, Isha angle: 18.
tehranInstitute of Geophysics, University of Tehran. Fajr angle: 17.7, Maghrib angle: 4.5, Isha angle: 14.
northAmericaReferred to as the ISNA method. This method is included for completeness but is not recommended. Fajr angle: 15, Isha angle: 15
otherFajr angle: 0, Isha angle: 0. This is the default value for method when initializing a CalculationParameters struct.

Madhab

ValueDescription
shafiEarlier Asr time (use for Shafi, Maliki, Hanbali, and Jafari)
hanafiLater Asr time

HighLatitudeRule

ValueDescription
middleOfTheNightFajr will never be earlier than the middle of the night and Isha will never be later than the middle of the night
seventhOfTheNightFajr will never be earlier than the beginning of the last seventh of the night and Isha will never be later than the end of the first seventh of the night
twilightAngleSimilar to SeventhOfTheNight, but instead of 1/7, the fraction of the night used is fajrAngle/60 and ishaAngle/60

Prayer Times

Once the PrayerTimes struct has been initialized it will contain members for all five prayer times and the time for sunrise. The prayer times will be instances of NSDate and as such will refer to a fixed point in universal time. To display these times for the local timezone you will need to create a date formatter and set the appropriate timezone.

let formatter = DateFormatter()
formatter.timeStyle = .medium
formatter.timeZone = TimeZone(identifier: "America/New_York")!

print("fajr \(formatter.string(from: prayers.fajr))")

Full Example

let cal = Calendar(identifier: Calendar.Identifier.gregorian)
let date = cal.dateComponents([.year, .month, .day], from: Date())
let coordinates = Coordinates(latitude: 35.78056, longitude: -78.6389)
var params = CalculationMethod.moonsightingCommittee.params
params.madhab = .hanafi
if let prayers = PrayerTimes(coordinates: coordinates, date: date, calculationParameters: params) {
    let formatter = DateFormatter()
    formatter.timeStyle = .medium
    formatter.timeZone = TimeZone(identifier: "America/New_York")!

    print("fajr \(formatter.string(from: prayers.fajr))")
    print("sunrise \(formatter.string(from: prayers.sunrise))")
    print("dhuhr \(formatter.string(from: prayers.dhuhr))")
    print("asr \(formatter.string(from: prayers.asr))")
    print("maghrib \(formatter.string(from: prayers.maghrib))")
    print("isha \(formatter.string(from: prayers.isha))")
}

Convenience Utilities

The PrayerTimes struct has functions for getting the current prayer and the next prayer. You can also get the time for a specified prayer, making it easier to dynamically show countdowns until the next prayer.

let prayerTimes = PrayerTimes(coordinates: coordinates, date: date, calculationParameters: params)

let current = prayerTimes.currentPrayer()
let next = prayerTimes.nextPrayer()
let countdown = prayerTimes.time(for: next)

Sunnah Times

The Adhan library can also calulate Sunnah times. Given an instance of PrayerTimes, you can get a SunnahTimes struct with the times for Qiyam.

if let sunnahTimes = SunnahTimes(from: todayPrayers) {
	print(dateFormatter.string(from: sunnahTimes.lastThirdOfTheNight)
	print(dateFormatter.string(from: sunnahTimes.middleOfTheNight)
}

Qibla Direction

Get the direction, in degrees from North, of the Qibla from a given set of coordinates.

let nyc = Coordinates(latitude: 40.7128, longitude: -74.0059)
let qiblaDirection = Qibla(coordinates: nyc).direction

Contributing

Adhan is made publicly available to provide a well tested and well documented library for Islamic prayer times to all developers. We accept feature contributions provided that they are properly documented and include the appropriate unit tests. We are also looking for contributions in the form of unit tests of of prayer times for different locations, we do ask that the source of the comparison values be properly documented.
